T (1. whom it may concern:

Be it known thatl, Hnxnr Hnss. a citizen of the Jni'ted States. and a resident of Philadelphia. in: the county of Philadelphia and State of Pennsylvania. have invented a races to move at different rates of speed.- For thisreason the separators-between the balls have heretofore been made flexible, permitting such slight variations.

A principal object of my invention. is to provide an improved separator. which is free from certain disadvantages ofseparators now in use. which takes up but littleroom in the races, is simple in structure. and provides the slight flexibility necessary in this class of bear-in by the use of a simple compressible member which at the same time may serve for the etiicient lubrication of the bearing.

My invention will be hereinafter more fully described with reference to the accompanying drawing. which illustrates certain exemplifying structures in which the said invention is embodied. and in which: Figure 1 is an end elevation of a ball bearing to which my invention is applied Fig. 2 is a detail view. partly in section, of one form of my separator. Fig. 3 is a fragmentary view of a bearing in which. links 12 are-used to connect the separators T.

Referring to Figs. 1 and Q. l is an inner bearing ring; 2. a bore in said ring by which the ring may be secured in any approved manner to an axle or shaft; 3, an outer bearing ring; 1, a ball race in ring 1; ,5, a ball race in ring 8. 6. a series of balls intermediate the-bearing rings and running in races 4 and 5; 7. the general designation of my separator; 8, side members of the same. twosuch side members beingoperatively connected to form one separator; 10, rivets pas ing. through the constricted portions 9 the separators and holding the two halves thereof together.

As assembled the separators have ateither .end a cup-shaped, or partly spherical. re-

cess loosely embracing a segment of a ball. The shape of the separators is such that when the bearing is assembled they are selfretained in position, and will not become accidentally disengaged from the balls.

11 is a piece of felt or other compressible or elastic medium placed in each portion 8 of. the separators, between the'side ieces 8 and the balls, and retained by the rivets 10 which pass through them.

The flexible medium 11 is preferably of felt. and'serves by reason. of its slight compressibility to permit the variation in spacing of the balls which is desirable in this class of bearing. and at the same time serves as an excellent retainer of lubri 'ant. which it carries in the most cfiicient manner in direct contact with the balls.

'Theseparators as above described when assembled are self-retained in position. and need not. be connected with each other. It is. however. desirable in certain cases to connect the separators. \Vlien they are connected the breakage of a ball will not be so liable toresult in the falling out of the separators. In Fig. 3 is shown a way in which the. separators may be connected.

12 are links each of which is secured atone end to one side of one of the separators by its rivet 1-0 and at the other end to the next separator in a similar-manner, thus flexibly linking all of the separators to gether.

Reference is made to applicants previous application Serial No. 265.385. filed June 15, 1905.

Having described my invention. what I;- claim is: I

1. In a ball bearing the combination two adjacent balls of a separator comprising a rigid sheet metal body having cup-*' shaped recesses presented toward the balls and an elastic substance placed in said recesses and engaging the balls and serving to form a yieldable medium between the rigid separator body and the balls.

'2. Tu a ball bearing. the combination of two bearing rings having ball races. balls running therein. and separators intermediate adjacent balls. each separator having .Of Jbea 'in g. rings provided" with -r aees,' {-a seriesrof balls) a. plurality ofi'ndependent 'i 'bmldingga baIL'dnd a yielding medium c-1' each. cup-portion directly contactingfwithtlie vball-, the zupsflqeing so formed as tb zillqwxthe balls-.flo he relatively close to" 'a'clj "other, and the combined conipressibilof the: yieldihg mediums zilloWing a jaentball .andaii elastic lilbricant carrymedium' interposed. gqtw'ee n" s'aid "sepa .mt'qr aridjfeach' adjacent 'aIL'I A I a bdll bear ing, in 'colilbing'tioii,' 21 3a if metallic dblgble e pip-shaped members; "time; i1'1te i'p'(' 'sed=between each two a ijace' t ballswith one of its cup-.poitign sv partly- $ur-' great degree ..,of qelative -.mi\"ement joi the balls in theiifi-pl'anefof rotation.
